Light brown discharge from wiping after urinating in early pregnancy may be due to vaginal leukorrhea or blood in the urine. In the early stages of pregnancy, the fertilized egg comes to bed, causing a small amount of bleeding from the uterine wall and, in sensitive people, soreness. If there are no obvious abnormal pathological symptoms such as itching and pain in the vagina or urethra, as well as more intense pain in the lower back and abdomen, there is usually no need to worry too much. However, if there are other obvious pathological changes, it is suspected that they may be caused by the following diseases. Since pregnant patients are in a special physiological period, if there are doubts they need to go to the hospital as soon as possible for examination and clear diagnosis: 1. Urinary tract infection: if there is light brown discharge after wiping in the early stage of pregnancy after urination, and the color of urine is also presented as light brown, and there are symptoms such as frequent urination, urgent urination and painful urination, it may be due to the pelvic and renal calyces, bladder, 2, vaginitis: if pregnant women appear light brown, foamy discharge, along with fishy smell, vulvar itching and other symptoms, it may be due to vaginal infection with pathogenic bacteria; 3, cervicitis: when pregnant women appear purulent light brown discharge, and have symptoms such as burning vulva and lumbar abdominal pain, consider that infection may occur in the cervical area, caused by Cervicitis; 4. Pre-eclampsia: In the early stages of pregnancy, the placenta is not yet well developed, chromosomal abnormalities or the presence of endocrine abnormalities and systemic diseases in pregnant women can easily cause pre-eclampsia. The symptoms are light brown vaginal discharge, vaginal bleeding, and paroxysmal pain in the lower abdomen; 5. ectopic pregnancy: if the pregnancy occurs in the fallopian tube, cervix, etc., patients may have light brown discharge and severe pain in the lower abdomen when miscarriage or rupture occurs. Patients can self-diagnose based on the above symptoms and should go to the hospital for examination in case of serious discomfort. In case of serious discomfort, the patient should go to the hospital for examination in time to prevent the vaginal or urethral lesions from getting worse, which may make treatment more difficult and may also have adverse effects on the fetus. In addition, pregnant patients should not take any medication without permission to avoid damage to the mother and fetus.
